Thanks Joe,

It seems the reason your process-level isn't returning any <li> tags is because there isn't a level 3. What's happening is you are outputting the <ul> before checking to see whether there is a value.

Yes, I should have made clear that I know I needed a test, but just didn't know *how* to do it.

Alas the below doesn't quite work. Besides needing to change the "<" to "&lt;", my level 2 bullets aren't getting applied now.

I think what you want to do is check to see if:

<xsl:if test="@level < following-sibling::bullet[(_at_)level][1]">
        <ul>
                <xsl:apply-templates/> <-- You'll have to edit this
        </ul>
</xsl>

Here's the complete stylesheet:

Because of limitations in the Keynote file format, I have relied on the new grouping functionality in XSLT 2.0. As such, you should use Saxon 8 to run it.
